Description

Technical Field

[0001] This utility model relates to the field of hair styling device technology, and in particular to a hair curling attachment and hair styling device. Background Technology

[0002] In related technologies, the hair curling attachment is the core styling component of a hair dryer or hair curling device. It is usually made of aluminum cylindrical components and has a hollow air cavity, an air outlet on the periphery, and an air inlet at the axial end. By inserting the air outlet of the hair dryer or hair curling device into the air inlet and wrapping the hair around the periphery of the hair curling attachment, the hair dryer or hair curling device can provide airflow through the air inlet and air cavity and blow it out from the air outlet to create curls.

[0003] During the actual research and development process, the inventors discovered that the periphery of the hair curling attachment is a smooth cylinder, and the air outlet is directly opened on the smooth cylindrical surface. When the user wraps hair around the surface of the hair curling attachment, the hair tends to stick tightly and completely cover the air outlet. This causes the hot air to accumulate inside the air cavity and cannot be effectively discharged when the user is styling hair with hot air. As this hot air accumulates inside the air cavity, the heat is transferred to the surface of the hair curling attachment, causing the temperature of the hair curling attachment to rise sharply. Once the user uses the hair curling attachment with high temperature for hair curling, the hair curling attachment is likely to come into contact with the scalp and burn the scalp, resulting in low user safety.

[0004] Therefore, it is necessary to research a new technical solution to address the above problems. Utility Model Content

[0005] In view of this, the present invention addresses the deficiencies of the existing technology, and its main purpose is to provide a hair curling attachment that effectively solves the problem of hair curling attachments easily burning the scalp, thereby improving the user's safety.

[0006] This utility model provides a hair curling accessory, including an aluminum tube body with a circular cross-section. The aluminum tube body has a hollow air cavity, which passes through the axial end of the aluminum tube body to form an air inlet. The outer peripheral side of the aluminum tube body has at least two protrusions, both of which extend axially and are arranged at a radial distance from each other to form a groove. The surface of the protrusions is provided with a first air outlet, and the groove is provided with a second air outlet. Both the first and second air outlets pass through the inner surface of the aluminum tube body to conduct and connect to the air cavity.

[0007] The beneficial effects of the hair curling accessory provided by this utility model are as follows: Compared with the prior art, firstly, by providing two protrusions on the outer peripheral side of the aluminum tube body, and forming a groove by the radial spacing between the two protrusions, and providing a first air outlet on the protrusions and a second air outlet on the groove; when the user wraps hair around the surface of the aluminum tube body to curl the hair, even if the hair blocks the first air outlet of the protrusions, air can still be blown out through the second air outlet of the groove; ensuring that hot air can be smoothly discharged, thereby significantly reducing the phenomenon of heating the aluminum tube body due to hot air stagnation in the air cavity, solving the defects of scalp burn and face burn caused by heating the aluminum tube body, and improving the user's safety performance;

[0008] Secondly, because it avoids heating the aluminum tube body with hot air, it prevents the heat generated by the aluminum tube body from directly contacting the hair. This can significantly improve the problems of protein deformation, charring and breakage, and loss of elasticity caused by high temperature contact with the hair, providing users with a safer and healthier hair care effect and styling experience.

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0034] Please refer to the following: Figures 1 to 4 The hair curling accessory 100 provided in the embodiments of this application will now be described. The hair curling accessory 100 includes an aluminum tube body 10.

[0035] The aluminum tube body 10 has a circular cross-section and a hollow air cavity 11. The air cavity 11 extends through the axial end of the aluminum tube body 10 to form an air inlet 12, specifically extending through the rear end of the aluminum tube body 10 to form an air inlet 12. The outer peripheral side of the aluminum tube body 10 has at least two protrusions 13, both of which extend axially and are arranged at a radial distance from the aluminum tube body 10 to form a groove 14. The surface of the protrusions 13 is provided with a first air outlet 15, and the groove 14 is provided with a second air outlet 16. Both the first air outlet 15 and the second air outlet 16 extend through the inner surface of the aluminum tube body 10 to conduct and connect to the air cavity 11.

[0036] Specifically, firstly, by providing two protrusions 13 on the outer periphery of the aluminum tube body 10, and forming a groove 14 with the two protrusions 13 arranged radially, a first air outlet 15 is provided on the protrusions 13 and a second air outlet 16 is provided on the groove 14; when the user wraps hair around the surface of the aluminum tube body 10 for hair curling, even if the hair blocks the first air outlet 15 of the protrusions 13, air can still be blown out through the second air outlet 16 of the groove 14; ensuring that hot air can be smoothly discharged, thereby significantly reducing the phenomenon of hot air stagnating in the air cavity 11 and heating the aluminum tube body 10, solving the defects of scalp burn and face burn caused by the aluminum tube body 10 being heated, and improving the user's safety performance; secondly, since the hot air can be prevented from heating the aluminum tube body 10, the heat generated by the aluminum tube body 10 can be prevented from directly contacting the hair, which can significantly improve the problem of protein deformation, charring and breakage and loss of elasticity caused by the hair contact with high temperature, providing users with a safer and healthier hair care effect and styling experience.

[0037] Understandably, since users need to wrap their hair around the surface of the aluminum tube body when styling curly hair, the only way to allow the hair to block the first air outlet and then blow air outward through the second air outlet is to create axially extending protrusions and form a groove between the two protrusions. If the surface of the aluminum tube body is provided with radial protrusions and radial grooves, the hair will still cover the radial protrusions and radial grooves and block the first and second air outlets when the user wraps their hair around the surface of the aluminum tube body. Therefore, only axially extending protrusions and axially extending grooves can be provided, and radial protrusions and radial grooves cannot be provided.

[0038] In some embodiments, the first air outlet 15 and the second air outlet 16 are any one or more combinations of circular holes, elliptical holes, axially elongated holes, radially elongated holes, square holes, triangular holes, or rhomboid holes. A plurality of first air outlets 15 are arranged in a row along the axial spacing of the protrusion 13; a plurality of second air outlets 16 are arranged in a row along the axial spacing of the groove 14.

[0039] Specifically, the first air outlets 15 arranged in rows have at least three rows arranged radially at intervals along the protrusions 13. These three rows of first air outlets 15 are defined as a first odd-numbered row 151, a first even-numbered row 152, and a first odd-numbered row 151. The first air outlets 15 of the first odd-numbered row 151 and the first air outlets 152 of the first even-numbered row are staggered. The second air outlets 16 arranged in rows have at least two rows arranged radially at intervals along the grooves 14. These two rows of second air outlets 16 are defined as a second odd-numbered row 161 and a second even-numbered row 162. The second air outlets 16 of the second odd-numbered row 161 and the second air outlets 162 of the second even-numbered row 162 are staggered one-to-one.

[0040] For example, the row of first air outlets 15 has three rows, namely, a row of first odd-numbered rows 151, a row of first even-numbered rows 152, and a row of first odd-numbered rows 151 arranged radially along the protrusion 13. The plurality of first air outlets 15 in the first odd-numbered rows 151 are staggered with the plurality of first air outlets 152 in the first even-numbered rows 152. The row of second air outlets 16 has three rows, namely, a row of second odd-numbered rows 161, a row of second even-numbered rows 162, and a row of second odd-numbered rows 161 arranged radially along the groove 14. The second air outlets 16 in the second odd-numbered rows 161 are staggered with the second air outlets 162 in the second even-numbered rows 162. This structure can significantly reduce the phenomenon that when hair is wrapped around the surface of the aluminum tube body 10, the hair completely blocks the first air outlets 15 and the second air outlets 16.

[0041] It should be noted that the number of rows of the first air outlet and the number of rows of the second air outlet can be set to one, two, three, four, etc., according to actual needs.

[0042] In other embodiments, the hair curling attachment 100 further includes a splitter 20, which is inserted into the air cavity 11 of the aluminum tube body 10 to securely install the aluminum tube body 10. The hair curling attachment 100 is plugged into a hair dryer or hair curling device via the splitter 20, allowing the hair dryer or hair curling device to provide airflow. This airflow passes through the air inlet 12 and the air cavity 11 and is blown out from the first air outlet 15 and the second air outlet 16, enabling the user to wrap hair around the surface of the aluminum tube body 10 for curling.

[0043] It is understandable that the air cavity of the aluminum tube body can penetrate through both ends of the aluminum tube body along the axial direction, with the air inlet at the rear end.

[0044] Specifically, the air distributor 20 includes a first mounting portion 21 and a second mounting portion 22 arranged along an axial distance. The first mounting portion 21 and the second mounting portion 22 are connected by a plurality of axial ribs 23. The plurality of axial ribs 23 are arranged in a radial array to form an air distribution zone 24. When the air distributor 20 is inserted into the air cavity 11 of the aluminum tube body 10, the plurality of axial ribs 23 can abut against the inner surface of the aluminum tube body 10, so that the protrusion 13 and / or the groove 14 are located within the coverage area of ​​an air distribution zone 24.

[0045] More specifically, each axial rib 23 can gradually tilt from the air inlet 12 toward the center of the air cavity 11 away from the air inlet 12, and multiple radial ribs 231 are set between each pair of axial ribs 23. The multiple radial ribs are set along the axial spacing. Through the set axial ribs 23 and radial ribs, the airflow in the air cavity 11 can be blown out evenly from each first air outlet 15 and second air outlet 16.

[0046] Preferably, the first mounting part 21 is provided with a first end cap 211, and the second mounting part 22 is provided with a second end cap 221. The first end cap 211 and the second end cap 221 can jointly clamp the aluminum tube body 10. The second mounting part 22 is provided with an insertion interface 222 penetrating its front and rear surfaces, and the insertion interface 222 is conductively connected to the air inlet 12. The outer surface of the first mounting part 21 is provided with a first insertion protrusion 212, the first end cap 211 is provided with a first insertion notch 2111 for the first insertion protrusion 212 to be inserted, the second end cap 221 is provided with a second insertion protrusion 2211, and the rear end of the aluminum tube body 10 is provided with a second insertion notch 17 for the second insertion protrusion 2211 to be inserted. With this structure, the first insertion protrusion 212 can be inserted into the first insertion notch 2111, and the second insertion protrusion 2211 can be inserted into the second insertion notch 17, thereby improving the installation reliability of the air distributor 20 and the aluminum tube body 10, and making it less likely for them to shake.

[0047] Furthermore, the second end cap 221 is pivotally connected to an iron clip 25 via a pivot. The iron clip can abut against the surface of the aluminum tube body 10, thereby clamping the ends of the hair wrapped around the aluminum tube body 10, thus assisting the user in styling curled hair and reducing the difficulty of styling curled hair.

[0048] In other embodiments, a hair styling device is also included, which is either a hair dryer or a curling iron. By inserting the air outlet of the hair styling device into the plug interface 222, airflow can be provided through the hair styling device. The airflow is blown out from the first air outlet 15 and the second air outlet 16 through the air inlet 12 and the air cavity 11, so that the hair wrapped around the surface of the aluminum tube body 10 can be curled and styled by these airflows.

[0049] Specifically, by installing the hair curling attachment 100, when the user wraps their hair around the surface of the aluminum tube body 10 to curl their hair, even if the hair blocks the first air outlet 15 of the protrusion 13, air can still be blown out through the second air outlet 16 of the groove 14; ensuring that hot air can be discharged smoothly, thereby significantly reducing the phenomenon of hot air being trapped in the air cavity 11 and heating the aluminum tube body 10. This solves the defects of the user's scalp being burned and face being scalded by hot air due to the aluminum tube body 10 being heated, and improves the user's safety performance.

[0050] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
